When we try to add HG8245 no matter what capacity profile we use we can't add the ONT to the system.
OLT version: SmartAX MA5600 V800R005C33B118HP1003
The ONT is always in "no resume" state and mismathes.
We can use the CLI command "ont resume resource resume" or do it from BMS like it’s shown in the attached screenshot. Then add the HG8245 with HG850a profile.
Even it is mismatch, OLT will force sending profile to ONT, and ONT will choose the parameters it can understand.
The only uncomfortable thing is that it still shows "mismatch".
One of the reasons is that HG8245 has 128 GEM ports but the OLT supports ONTs with only 32.
If we don't know the real capabilities of some ONT we can add it first with some profile (for example the profile for HG850a) and then execute the following command:
huawei(config-if-gpon-0/3)#display ont capability
After you query this information you can try to create a proper profile.
Anyway in our case this didn't help us.
